Hi Devs, I'm trying to add some functions from the BAD extension to AsterixDB. I found there are two ways of adding runtime entities into the FunctionCollection: 1) Adding an IFunctionRegistrant, 2) Implementing an extension function manger. However, I didn't find a way to add functions to Metadata. I wonder there is an existing method for doing so? I did something similar to the IFunctionRegistrant in the MetadataBuiltinFunctions on my branch. If we don't have an existing method, I can try to create a patch on this.
Best, Xikui
